SIPHN WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 792,805, dated June 20, 1905.

l Application 'tiled December 23, 1904:. Serial N0. 238,038.

T0 all whom, it may concern.-

Be it known that we, ROLLIN O. WILSON, residing at Mount Vernonestchester county, New York, and WILLIAM H. SCHULTE, residing at Trenton, Mercer county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Siphon Water-Oloset Bowls, of which the following is a full, clear, and exact description.

This invention relates to siphon water-closet bowls and the like and to a new method of establishing siphonic action therein.

The main object is to provide a simple means for and an eiiicient method of establishing in a device of the character described a siphon which serves to quickly and thoroughly empty the bowl.

Another object of this invention is to provide against overiiow.

In the accompanying drawing the single figure is a vertical sectional view of this invention as applied to water-closet bowls.

l is the bowl proper.

2 2 are discharge pipes or passages. Each dischargepassage projects upwardly from a point near the bottom of the bowl to form a trap. These passages then turn downwardly and meet at a common point adjacent to the outlet 3. The trapped portions of the disharlge-pipes are approximately at the same eve In the drawing the normal water-level withivrite bowl is indicated by the dotted lines et is a passage through which water is supplied to the bowl.

When it is desired to iush the bowl, water is let in until it overflows into the downward bends of the pipes 2 2. The separate bodies of water thus owing through said pipes meet at a common point adjacent to the outlet 3 and form a water plug, so called, which as it descends through the outlet 3 creates a partial vacuurn in the discharge-pipes 2 2 and establishes a siphon, the force of which then quickly and effectively empties the bowl. This siphon is maintained until the waterlevel descends to a plane where air is admitted to the discharge-pipes, whereupon the siphon is broken and the bowl is again filled to its normal level with fresh water. Normally the water in the bowl projects sufficiently far into the trapped portions of each discharge-pipe as to form an effective seal. The plug is formed by the meeting of the waters at a common point, and this occurs at such a location relatively to the outlet 3 that the siphonic action is quickly established.

It should be understood that the proportions and the particular number or arrangement of the discharge-pipes may be varied as desired so long as the discharged waters flowing down from different directions are brought together so as to establish the aforesaid plug.

An important feature of this invention is that should one of the discharge-pipes become clogged partially or completely there is no danger of overfiowing the bowl, since another outlet or orifice is provided for the dis.- charge of the contents.

The simplicity of the arrangement permits of the ready cleansing of the pipes should either of them become clogged.

What is claimed is 1. In a siphon water-closet bowl and the like, a bowl means to conduct the discharged waters from different points to a common meeting-place, an outlet-passage adjacent thereto.

2. In a siphon water-closet bowl and the like, a bowl a plurality of outlet-passages leading from near the bottom of the bowl to a common point, an outlet adjacent thereto.

3. In a siphon water-closet bowl and the like, a bowl a plurality of discharge-passages leading from near the bottom of the bowl to a common point, an outlet adjacent thereto, a trap in each of said passages.

4. In a siphon water-closet bowl and the like, a bowl a plurality of discharge-passages leading from near the bottom of the bowl upwardly to the same level, and then turning downwardly and arranged to meet at a common point whereby a plurality of currents of water will be brought together, an outlet adjacent thereto.
